Yes, I don't know how many times I've looked trough google, cosp.com, deviant, photobucket, and whatever site you can imagine, to find some masked characters.

I like masks.
Helmets work too.
So, if you feel like you know a characters that wears a mask that isn't listed, feel free to spit out some suggestions : D
So, characters from Games, anime and manga are places the characters can come from, not movies and stuff like that (we don't really have any con that have movies/ anything other than "JAPAN!!!ZOMG" as theme except like... one...

[Edit]: ehe? WTF, I thought I said that I wasn't interested in Gundams...
Why?
Because I don't know where to start dammit D: It's like... XXX different titles with gundams...

of course I can't come up with every character I know of when I actually start a thread...

*Editing first post as I come up with more characters/ someone posts some*

and I put this under props since masks > props or whatever...
[Edit31/8-2009]: I think I'm gonna do a "helmet > Games" "mask >Games/anime,etc" to get some control of everything...

And if you're wondering "why didn't he add my character to the list?" It's probably because I can't find any pictures of it. I google(!) every character to see the mask/character, but if I don't find any... I don't wanna add maskless characters to the list... ..'

[Edit]: ok, some might have ended up in the wrong category since the thread suddenly EXPLODED with suggestions : D Thanks

[Edit3/4-2010]: Categorized them in the right order... now, trow some more suggestions at me.

Oh, and Raphael from Soul Calibur has a masked costume. Though it's kinda... fruity. And Altair and Ezio (I think that's his name) from Assassin's Creed don't have masks, but their hoods cover the majority of their faces~
